SPEED WRENCH.

Application filed October 4, 1926. Serial No. 189,490.

This invention relates to wrenches generally and has for its primary object the provision of means capable of receiving a force or impulse necessary to setting up a turning movement of the stock or shank of the wrench and wherein said means are characterized by mechanism functioning by the action of inertia to automatically cause rotation of the stock to continue through an uncertain interval of time.

My invention is further characterized by means that will greatly facilitate the labor of releasing tightly bound nuts and enable the task to be carried on with utmost dispatch.

Another object of the invention is to provide a wrench of this character which is simple of construction; inexpensive of manufacture, positive of action, and one which is strong and durable.

W'ith the above and other objects in view which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fullv described'and particularly pointed out in the claim.

In the accompanying drawings has been illustrated the preferred form of the invention, it being, however, understood that no limitations are necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

Fig. 1 is a view in side elevation of the wrench,

Fig. 2 is a section on line 22 of Fi 1, and

Fig. 3 is a sectional perspective view of a portion of the stock. a

It should be understood that While I have combined my invention with certain characterizing elements of'a wrench structure, I have resorted very largely to the present showing; as illustrative of one practical eml'iodiment of the invention, and that I do not wish to be limited to the exact arrangement of parts herein shown and described. However, the. combination as shown, is in my opinion highly useful and novel, and it should not be understood that I desire to sacrifice any part of the invention, nor that I am to be limited to the exact arran ement of parts herein shown and described In practice, I employ a stock 5 having a nut engaging socket or portion (3 at one end and a removable breast piece 7 at its opposite end, the latter being supported on the. cylindrical end portion of the stock so that it may be held stationary while the stock is revolved. The socket 6 is also of the removable type and is supported on a square portion of the end of the stock.

Between the ends of thestock is an enlargement 8 preferably fori'ned integral with said stock and, at each side, said enlargement is provided with a reduced flat faced extension 9, either of Which is adapted to fit in the corresponding; openin e 10 in the central portion of weight means 11.. Said means is in the form of two or more arms 12-12 which radiate from the stock 5. Each of said arms is formed at its outer end with a relatively heavy weight 13. The arms are relatively of the same length in order that balancing action is had when the stock is set in motion. The arms each extend for such distance beyond the axis of the stock as to contribute the maximum measure of leverage force to the stock when power is directed to a particular one of said arms.

It follows that the said means 11 is adapted to revolve with the said stock and thatatter thesockct 6 is engaged with the nut to be operated upon, one of said arms 12 at the weight end thereof can be struck by the hand of the operator so that great leverage power is conveyed to the stock that will result in an in stant breaking down of the nut or a loosing of same from its bolt. The force thus applied to the stock is sufficient to cause the latter to continue to revolve by inertia of the respective Weights 13. After the nut is loosened in the manner set forth, the arms 12 may be tapped periodically to maintain rotary 1notion of the stock until the nut is entirely removed from its bolt.

I claim:

- In a device of the type described, a stock having a non-circular portion of greater diameter than said stock, a transverse member having a non-circular aperture formed therein for removably receiving said portion, said member being entirely removable from 'said stock, and a breastplate removably secured to said stock.
